So now non-trailing SourceMappingURL comments are matched as well.

So now they are matched also when they appear on the same line as code.
Removed: The .set() method. I couldn’t decide how it should work
 considering the above change. Moreover, it was unnecessarily complex (and
 would have gotten worse) for very little gain. It is much easier to run
 .remove() if needed, and then simply code += "\n//# sourceMappingURL=" + url (using the appropriate comment syntax and newline). KISS.
Changed: The .insertBefore() method now always inserts the string exactly
 before the sourceMappingURL comment; not before the newline before the
 comment (if any). Moreover, it does not ensure that the comment will be on a
 new line anymore. This is up to the caller. KISS.
Changed: The .remove() method no longer removes the newline before the
 sourceMappingURL (if any).
Changed: Renamed .get() to .getFrom().
.remove() to .removeFrom().Added: The .existsIn() method.
